A simple microwave-assisted hydrothermal approach is adopted to synthesize VO 2 ·0.26H 2 O nanobelts@reduced graphene oxide (VO 2 ·0.26H 2 O@rGO), which is regarded as a promising cathode material for ZIBs. Compared to VO 2 ·0.26H 2 O, VO 2 ·0.26H 2 O@rGO has a large specific surface area and low charge transfer resistance, improving its electrochemical properties. The large lattice spacing, high capacitive Zn 2+ storage behavior, fast Zn 2+ transfer rate and stable structure are also responsible for the performance.
